IPM for Pennsylvania Schools A How-to Manual

Produced by the Pennsylvania Integrated Pest Management Program

College of Agricultural Sciences Cooperative Extension

Pennsylvania Department of Agriculture

The PA IPM Program is a collaboration between the Pennsylvania Department of Agriculture and The Pennsylvania State University aimed at promoting Integrated Pest Management in both agricultural and nonagricultural settings.

As part of the PA IPM Program, the Pennsylvania Department of Agriculture, the Pennsylvania Department of Education, the Pennsylvania Department of Health, and The Pennsylvania State University Colleges of Agricultural Sciences and Education signed a memorandum of understanding to promote IPM implementation in schools. PA IPM drew on this partnership to develop this manual.

4. Set Action Thresholds The mere presence of a pest does not always require the application of a pesticide. The pest manager and school staff should decide in advance how many pests are harmless and how many require management (in other words, how many can be tolerated). This is called the “action threshold” for management of a particular pest. IPM for Pennsylvania Schools

5. Identification and description of your school pest problem(s). The ABC Middle School has historically had problems with ants and mice. Our pest management contractor has identified these pests as pavement ants and house mice. The mice are usually noticed in the fall as the weather cools off, while the ants are seen throughout the school year. There has been a problem with staff and students leaving food wrappers and crumbs in various locations. Current control efforts have been reactive and not effective. The school plans to set up a monitoring program using glue boards for the mice and sticky traps for the ants to detect and pinpoint infestations or hot spots. Maintenance personnel and staff and students will be instructed concerning food waste sanitation. Pest reporting sheets will be provided to each classroom and the kitchen area and will be checked on a regular basis by John C. Ustodian (IPM coordinator). IPM for Pennsylvania Schools 16

6. Description of your school IPM Information Flow (communication strategy) and Training Format. John C. Ustodian (IPM coordinator) will meet monthly with Ima Beatle (pest management contractor) to cover monitoring reports. An initial meeting will be held on January 23 to establish a pest activity log binder. The log binder will be kept in the main office of administration and pest activity sheets will be distributed to teachers and staff. The sheet will indicate identification of pest(s) (if known), number seen, date, time, and location. The assistant principal, Ura Friend, will be responsible for notifying John C. Ustodian of logged pests from staff. Ima Beatle (pest management contractor) will respond to log complaints. If any sanitation or structural changes are needed, it will be written in the log along with remedial recommendations. Specific service reports will also be placed in the log binder that documents particular actions taken by the pest management contractor. Staff, teachers, and students will be instructed on how to log pest complaints and be given a brief overview on pest identification and the conditions that promote the pests. Pamphlets and fact sheets will be made available at the time of training and/or posted on bulletin boards in specific areas, such as the cafeteria and teachers’ lounge. This information will focus on pest reduction strategies connecting people’s behavior—such as overwatering plants, eating at desks, leaving crumbs on the floor, etc.—to pest problems. More specific training will be held annually and separately for maintenance and kitchenstaff.

7. A record of pesticide(s) applied on school property. Ima Beatle is our licensed pesticide contractor (BU-00000). Indoors, ______, a bait box, will be used to control the ants. For emergency situations, ______will be used to control flying stinging insects such as wasps.

8. A record of nonpesticide actions taken on school property. Whenever practical, nonpesticide means to manage or limit pests will be used. Ima Beatle (pest management contractor) will perform a thorough inspection and provide the IPM committee with a report identifying conditions that are contributing to our ant and mouse problems. Sanitary/ housekeeping deficiencies will be reported as well. Once this is done, a priority list will be generated to optimize a plan of corrective actions such as sealing openings with caulk and copper mesh, repairing leaks and screens, reducing clutter, and organizing stored goods so they are kept off the floor and away from walls. Mechanical traps will be used to reduce pests.

9. Evaluation of your school IPM program. At least once a year, the IPM committee will meet with the pest control contractor to evaluate the success or failure of this IPM plan.

10. A description of the location of your school IPM plan and records. A copy of this plan, annual evaluations, pest control contractor recommendations, and pesticide use records will be kept on file in the main office.

Sample Notification Letter for Parents or Guardians (To be sent to all parents or guardians of students enrolled in the school at the beginning of each school year.)

The ______School District uses an Integrated Pest Management (IPM) approach for managing insects, rodents, and weeds. Our goal in using this approach to pest management is to protect every student from pesticide exposure. Our IPM approach focuses on making the school building and grounds an unfavorable habitat for pests by removing food and water sources and eliminating their hid- ing and breeding places. We accomplish this through routine cleaning and maintenance. We routinely monitor the school building and grounds to detect any pests that are present. The pest monitoring team consists of our building maintenance, office, and teaching staff and includes our students. Pest sightings are reported to our IPM coordinator, who evaluates the “pest problem” and determines the appropriate pest management techniques to address the problem. The techniques can include increased sanitation, modifying storage practices, sealing entry points, physically removing the pest, etc.

From time to time, it may be necessary to use pesticides registered by the Environmental Protection Agency to manage a pest problem. A pesticide will only be used when necessary, and will not be routinely applied. When a pesticide application is necessary, the school will try to use the least toxic product that is effective. Applications will be made only when unauthorized persons do not have access to the area(s) being treated. Notices will be posted in these areas 72 hours prior to application and for two days following the application.

Parents or guardians of students enrolled in the school may request prior notification of specific pesticide applications made at the school. To receive notification, you must be placed on the school’s notification registry. If you would like to be placed on this registry, please notify the district in writing. Please include your e-mail address if you would like to be notified electronically.

If a pesticide application must be made to control an emergency pest problem, notice will be provided by telephone to any parent or guardian who has requested such notification in writing. Exemptions to this notification include disinfectants and antimicrobial products; self-containerized baits placed in areas not accessible to students; gel-type baits placed in cracks, crevices, or voids; and swimming pool maintenance chemicals.

Each year the district will prepare a new notification registry.

If you have any questions, please contact ______, IPM coordinator.

Sincerely, IPM for Pennsylvania Schools 24

Carta de Notificación para Padres y Tutores (Para ser enviada a todos los padres y turores de los estudiantes matriculados en la escuela al comienzo de cada año escolar)

El Distrito Escolar ______utiliza el método Integrado de Control de Plagas (Integrated Pest Management, IPM por sus siglas en inglés) para el manejo de insectos, roedores y mala hierba. Nuestra meta es proteger a cada estudiante a la exposición de pesticidas utilizando este método. El método IPM se enfoca en hacer del edificio escolar y sus alrededores un hábitat no favor- able para estas plagas al remover sus fuentes de alimento y agua y eliminando los lugares donde se esconden y reproducen. Esto se logra a través de una rutina de limpieza y mantenimiento. Con regulari- dad se inspeccionan el edificio y sus alrededores para detectar si hay plagas presentes. El grupo de con- trol d plagas compone del personal de mantenimiento del edificio, de oficina y profesores y maestros e incluye a nuestros estudiantes. De detectar la presencia de plagas, se informa al coordinador del IPM, el cual evaluará y determinará la(s) técnica(s) apropiada(s) para manejar dicho problema. Las técnicas pueden incluir incrementar la limpieza, modificar las prácticas de almacenamiento, sellar puntos de entrada, físicament remover la(s) plaga(s), etc.

De tiempo en tiempo, puede haber la necesidad de utilizar algún pesticida registrado por la Agencia de Protección Ambiental (EPA) para manejar y/o controlar el problema de plagas. En estos casos, se uti- lizará solamente cuando sea necesario sin aplicarlo con regularidad y solo se usará la cantidad mínima que sea efectiva. Las aplicaciones se harán cuando no haya personal no autorizados en las áreas donde se utilizará el producto tóxico. Notificaciones serán puestas en las áreas que serán tratadas 72 horas antes de la aplicación y se dejarán por dos (2) días después del tratamiento.

Los padres o tutores de los estudiantes matriculados pueden solicitar que se les envíe una notificación previa de los pesticidas específicos que se aplicarán en la escuela. Si desean recibir esta notificación, sus nombres deben aparecer en la lista del registro de notificación de la escuela. Si deseen estar en la lista del registro, tienen que notificarlo al Distrito Escolar por escrito. Favor de incluir su dirección del correo electrónico si desea ser notificado (a) electrónicamente.

En caso de tener que aplicar algún pesticida para controlar una emergencia de plaga(s), la notificación se proveerá por teléfono a los padres o tutores que hayan solicitado dicha información por escrito. Las excepciones a esta notificación incluyen: desinfectantes y productos antibacteriales y microbiales, car- nadas en contenedores cerrados puestos en áreas no accesibles a estudiantes, carnada tipo gelatina que se coloca en rendijas y grietas, y los químicos que se utilizan para el mantenimiento de las piscinas.

Cada año, el Distrito Escolar preparará un nuevo registro de notificaciones.

Si tiene alguna pregunta, favor de comunicarse con ______, Coordinador IPM.

Atentamente,

They live in colonies whose mem- bers are divided into three castes: workers, queens, and males. The workers enlarge and repair the nest, forage for food, care for the young and the queen, and defend the colony. The queen lays eggs, and the males serve only to mate with the queens. Ants pass through four stages of development: egg, , , and adult. After mating with males, queens lay eggs that hatch into blind, legless larvae. The larvae Carpenter Ant are fed and cared for by worker ants. At the end of the larval stage they turn into pupae, which do not feed.

A bait pan is placed beneath the cone. Make sure the top edge of the bait pan is above the bottom edge of the trap. The top also is made of screening, and should be hinged (to empty the trap) and closed with a hook and eye.

Fly Bait Recipes

Bait is important to the performance of the trap. Here are some recipes and tips on using them.

Beltsville Bait (from Pickens, et al., 1994) This makes a dry bait that can be easily stored for a considerable time. It must be mixed with water before using.

Ingredients 1 pound granulated sugar 1 pound baking powder (double-acting type) 2 ounces dry active yeast (baking yeast) 6 ounces air-dried blood or freeze-dried fish meal

1 ⁄4 cup honey 2 tablespoons* water *Quantity of water needed may vary with the humidity of air when mixing. Use only sufficient water to bind dry ingredients together when they are compressed.

Procedure Mix ingredients thoroughly. Press mixture into a plastic ice-cube tray to form cubes. Invert the tray to dump the cubes, and let them dry to form hard blocks. To use the bait, add 2 cubes of bait to 2 quarts of water. Place bait in a wide-mouth pan beneath a cone-type trap. Flies are attracted to this bait from only a short distance, so traps should be placed within 6 feet of areas where flies are active. Bait pans should be cleaned and baited every 1 to 2 weeks and should be kept filled with water. IPM for Pennsylvania Schools 64

Liquid Yeast Bait (from Satrom and Stephens, 1979) This recipe makes 7–9 portions of liquid bait for use with a cone trap. It can be stored 20–30 days once it is ready for use.

Ingredients 2 quarts tepid (not hot) water (95°–105° F) 1 cup and 3 ounces active dry yeast (baking yeast) 2 tablespoons ammonium carbonate (optional*) *Ammonium carbonate is available from chemical supply houses and will improve the odor of the bait.

Mixing the bait Use a plastic (not glass) narrow-necked gallon jug with a screw cap for mixing, ripening, and storing bait. Bleach or milk jugs work well. Wide-mouth containers will not produce effective bait. Mix all the above ingredients in the jug. Important: With cap lightly sealed, allow mixture to begin to ripen (see ripening instructions below). It will foam up at first. After it subsides (1–2 days), tighten the lid and continue ripening till very smelly (2–9 additional days). Gases must escape while bait is foaming up (loose cap), but bait must finish ripening without air (tight cap) to attract flies.

Ripening the bait Allow bait to ripen 4–10 days in a place where temperatures remain above 60°F during the night and day. Bait is ripe when it is very smelly, with a musky, penetrating odor. Warm daytime temperatures will make up for slightly cooler (less than 60°F) nights, but in general, the warmer the average temperature, the faster the bait will ripen. Because of its heavy odor, the bait should be ripened in a well-ventilated area where it will not offend people. Do not ripen or store the bait in direct sunlight. Extreme temperatures can build within the jug, kill the yeast, and cause gases to expand enough to pop off the lid or break the jug.

Storing the bait To maintain potency, store bait with the cap kept tight. Open the jug only when necessary to refill the bait pan. Do not store in direct sunlight. note: Ripened bait should be treated as a decaying food material. It can cause gastrointestinal disturbances if ingested.

Using the bait Stir or shake the bait supply each time before adding to the bait pan. Pour about 1 cup (8 ounces) of bait in a wide pan on a level surface under the trap. Be sure the edge of the pan is higher than the bottom edge of the trap frame. The bait is effective in the pan for at least 3 to 5 days. It attracts more flies on the first day, and then gradually declines thereafter. Don’t let the bait dry out.

Moth Flies (Drain Flies) 1 1 Moth flies Psychoda( spp.) are about ⁄16 to ⁄4 inch long, fuzzy, dark or grayish insects. Their body and wings are densely covered with hairs. Wings, appearing too large for the body, are held roof-like over the body when at rest, giving a mothlike appearance. During the day, adults often rest in shaded areas or on walls near plumbing fixtures and on the sides of showers and sinks. During the evening, these flies can be seen walking about drains and sinks.

An endophyte is a fungus that grows inside a plant, and research has shown that turfgrass species containing endophytes have enhanced resistance to surface feeding insects, including chinch bugs, sod webworms and bill bugs.

The jaws are brown and the legs are very smooth, with the front legs longer than the rear. The egg sac is a white, paper-like disk usually placed in a protected area, such as under a stone. They enter buildings principally in the early fall and are active for several months. They make small white webs in confined spaces where they spend the winter. In spring, they usually emerge from their white web cells and find their way outside. Outdoors, they do not build webs but instead construct a flat tubular sac opened at both ends inside rolled leaves or crevices, or under loose bark or stones.

Ticks The height at which questing occurs determines the size of the host. When finally engorged, they drop off introduction to lay as many as 6,000 to 7,000 eggs. Ticks are important because they can transmit human diseases. They are not insects but relatives of spiders. When feeding, the tick uses its “teeth” (chelicerae) to Adult ticks have 8 legs and insects have 6. Ticks are cut the victim’s skin and then inserts its mouthparts.

Groundhog tick is the least commonly encountered of the four species listed here. It resembles the blacklegged tick and is about the same size. It is host-specific for groundhogs, but can be found on birds, small animals, or humans.

You can use the checklist at the end of this chapter to confirm the thoroughness of an inspection performed by a professional. Inspect both the inside and the outside of the buildings. If a professional is hired to do the inspection, ask to see locations that were infested and/or were found to have damaged wood. Discovering subterranean termite tubes or beetle damage is not necessarily evidence of an active infestation. Termite tubes or beetle exit holes or frass indicate only that termites or beetles were there at one time. In the case of beetles, the adults that made the exit holes may have been the last beetles that will ever emerge if they are from a species that does not reinfest wood.

The Pesticide Control Act of 1973 still requires acts under the supervision of a certified applicator who records be kept by the applicator for swimming pool is responsible for the applications and is available when maintenance chemicals and baits and gels for the three- year period. The new act does not change this. Frequently Asked Questions 127

Request for Proposal (RFP) or Contract Guide Specifications Q. Where can I get a sample copy of an RFP or contract guide specifications to provide potential pest management professionals for bidding purposes? A. There is a sample in IPM for Pennsylvania Schools: A How-to Manual and posted on the Web at paipm.cas. psu.edu/schoolmn/postform.doc.

Students Q. Does the term “student” include adult night school students for the purpose of notification? A. Act 2002-36 specifies that notification must be given to workers in the school building and parents and guardians of enrolled students. Many adult classes meet only once or twice a week. The PDA suggests that the district give the adult students in those night classes the opportunity for notification by informing the district, in writing, of their desire to be placed on the district’s notification registry, but the legislation is silent on this.

Visiting Schools Q. Is notification required for a visiting school coming to a sports event or other activity? A. Notification is required for workers in the building and for parents and guardians requesting it for their students who attend the school. Posting signs serve as notice for any other visitors to the school. The 7-hour reentry time for the area is still in effect. IPM for Pennsylvania Schools 128

What Is the Worker Protection Standard (WPS)?

The Worker Protection Standard (WPS) is a federal law • protection against exposure to pesticides with which all states must comply. In the Commonwealth, • ways to mitigate exposures to pesticides these regulations are also enforced by the Pennsylvania Department of Agriculture. Under the WPS, schools must • access to treatment if a pesticide exposure is suspected comply to ensure a safe work environment. The WPS is Most WPS requirements apply to all agricultural a regulation issued by the U.S. Environmental Protection workers or pesticide handlers, but there are some that Agency (EPA) that covers all restricted- and general-use only apply to certain persons such as those who handle pesticides used in the production of agricultural plants pesticide application equipment or clean pesticide- on farms, forests, nurseries, and greenhouses.

Mitigation • Provide decontamination supplies—water, soap, single-use towels, and spare overalls • Provide emergency transportation to the hospital for employees who have been exposed to pesticides To help growers and schools that produce agricultural crops comply with the WPS, the Rural Health Farm Worker Protection Safety Program was created and is located in the Pennsylvania Office of Rural Health at Penn State (porh.psu.edu/fwpp). This program is funded by the Pennsylvania Department of Agriculture’s Bureau of Plant Industry. The program is run in collaboration with the Penn State Pesticide Education Program and offers: • WPS training to farmers and growers • Handler and Worker WPS training in language appropriate sessions • Farm WPS evaluations to help the grower be in compliance with the WPS standard • Working with grower groups to assist them in their concerns • Working with farm labor groups in addressing their concerns The Pennsylvania Department of Agriculture (PDA) is responsible for the enforcement of the WPS in the Com- monwealth. The EPA has requested that PDA increase the number of WPS compliance inspections to ensure that the WPS is being followed. As a result, inspectors completed more than three hundred WPS enforcement inspections last year. Schools are included in these inspections if they all under WPS criteria.
